New efficient rendering engine

A lot of technical know-how has been invested in the completely new rendering engine which is the base for drawing large graphs efficiently. The new engine clears the way for many of the new visualization features described on the following pages. It has build-in support for color icons (in GIF, XPM and BMP format), used for drawing graph nodes.

Furthermore, the new rendering technology offers more comfort from the users point of view. For example, invisible dummy nodes (that filled up long multi-level spanning edges) are now highlighted automatically if they are touched by the mouse pointer, so moving them is much easier than before.

With the new rendering engine, memory consumption has been reduced significantly which is important for drawing very large graphs. Several memory leaks, present in all previous versions, have been removed, enabling long-lasting operation which was not possible before.
